JOHN T'oNEit, or NEW YORK, N. Y.

' Application filed June 7,

To all whom it may concern i Be it known that I, JOHN J (TONER, acitizen of the United States, and a resident of the city of New York,borough of Manhattan, in theconnty: and State of New York, have inventednew and useful Improvements in Rudders, of which the following is afull, clear, and exact description.

This invention relates to rudders for use in the navigation of screwpropelled vessels.

In the art of navigation great attention has been directed to thedevelopment of devices that facilitate the manceuvering of vessels. Forordinary purposes devices which give navigators great control of theirvessels are valuable in that they decrease the danger of loss of vesselsventuring into unknown harbors and sailing in busy waterways. When weconsider the art of naval warfare the capacity of manoeuvering is ofextreme importance and so devices that give great control of war vesselsare in demand.

The general object of this invention is the provision of a simple andeflicient rudder for use in conjunction with vessels that may beoperated to decrease the speed of the vessel and to serve as a reversingdevice.

This object is accomplished by mounting a rigid casing, open at bothends, in alinement with the screw propeller, and, associating with thecasing, means for closing the passage through the same so as to convertthe rudder into a reversing device.

This and other objects of the invention will be more clearly understoodfrom the following detailed description and accompanying drawings, inwhich Figure 1 is a side elevation of the stern of a vessel showing asection of the rudder;

Figure 2 is a section on the line 2-2, Figure 1;

Figure '8 is a section along the line 3-3, Figure 1;

Figure 1 is a top plan view of a horizontal section of a modified fromof the rudder; and

Figure 5 is a section along the line 55, Figure 4.

Referring to the above-mentioned drawings, a vessel 10 is shown providedwith a screw propeller 11 mounted on the driving shaft 12. Extendingrearward from the bottom of the vessel is a skag 13. Rotatably mountedin the bearing 14 attached to the ship is a hollow rudder post 15 towhich the rudder assemblage 16 is attached, The rud- 1922; Serial No.566,561.

derassemblage cosists ofa U-shaped plate 17 having a plate 18 attachedto its lower edges, as shown in Figure 8. Hinged to the plate 17 at 19is a. plate 20. Extending from a lug 2l-atta'ched to the -plate 20 is achain 22.which is guided by the roller 23 into the hollow post 15.Mounted on the top of the vessel is a roller 24 over which the chain 22passes. The plate 18 has a pintle 25 attached thereto which is mountedin a bearing formed in the skag 13.

When the vessel is in operation and pro gressing forward, its course maybe guided by means of the rudder 16, which consists of a casing open atboth ends, the casing being constructed from the plates 17 and 18. Therudder may be rotated about the vertical rudder post by any well knownmeans such as those commonly used with vessels. The water acted'upon bythe screw propeller 11 is forced through the rudder 16. If it is desiredto delay the movement of the ship, the plate 20 is raised by means ofthe chain 22. When the rudder is closed by means of the plate 20, if ithas been properly designed the action of the water upon the same as itis forced backward by the screw propeller 11 will cause the ship to stopand finally to move astern.

The rudder described in the preceding paragraphs may be made in manydifferent shapes and many different devices may be provided for closingit. A modified form is shown in Figures 4 and 5. In this case the rudderconsists of a cylindrical casing 26, open at both ends, mounted inalinement with the screw propeller 11. It is supported by the hollowrudder post 15 and the skag 13. Two semicircular gates 27 and 28 aremounted in the casing 26, one supported by a sleeve 29 rotatably mountedin the hollow post 15 and the other by a shaft 80 rotatably mounted inthe sleeve 29. These gates 27 and 28 may be operated by means of tillersattached to the sleeve 29 and the shaft 30. Other means might beprovided for operating the same but as this is no part of the inventionit will not be set forth in detail.

The operation of this modification is the same as that of the preferredform described above.

I would state in conclusion that while the illustrated examplesconstitute practical embodiments of my invention, I do not limit myselfstrictly to the exact details herein illustrated since manifestly thesame can be considerably varied without. departing ifrom the spirit ofthe invention as defined in the apgended claims.
